 determine, for each playback position of the video, particular display range information to be provided to a terminal device, the particular display range information indicating a display range including one or more regions having highest display frequencies among the determined display frequencies. 
   
     
     
         2 . The information processing device according to  claim 1 ,
 wherein the controller is further configured to:
 determine an average display frequency for each playback position by averaging a plurality of the display frequencies determined for the each region included in the display range indicated by the display range information; and 
 determine, from among a plurality of pieces of the display range information stored in the storage device, one or more pieces of display range information respectively indicating one or more display ranges having highest average display frequencies among the determined average display frequencies, as the particular display range information to be provided to the terminal device. 
   
     
     
         3 . The information processing device according to  claim 1 ,
 Wherein the controller is further configured to:
 generate a table for registering the determined display frequency for each playback position and region; 
 calculate, for each of the plurality of pieces of display range information stored in the storage device, a sum of the display frequencies for the each region included in the display range indicated by each of the plurality of pieces of display range information based on the generated table; 
 determine, as an attention degree, a value obtained by dividing the sum of the display frequencies by a number of the regions included in the display range indicated by the display range information, for each of the plurality of pieces of display range information stored in the storage device; and 
 determine, from among the plurality of pieces of display range information stored in the storage device, one or more pieces of display range information having highest attention degrees, as the particular display range information to be provided to the terminal device. 
   
     
     
         4 . The information processing device according to  claim 1 ,
 wherein the controller is further configured to:
 determine, for each playback position, a display range with a region having a highest display frequency as a center thereof or a display range with a median point of a plurality of the regions having highest display frequencies as the center thereof; and 
 determine display range information indicating the determined display range for each playback position as the particular display range information to be provided to the terminal device. 
   
     
     
         5 . The information processing device according to  claim 1 ,
 wherein the controller is further configured to determine the particular display range information indicating the display range including the one or more regions having highest display frequencies as display range information indicating a display range of a second video as a candidate to be displayed in the main view, the second video corresponding to a video identical to a first video displayed in a main view of the display of the terminal device and displayed in a sub view of the display.   
     
     
         6 . An information processing method adapted to be implemented on a computer, the method comprising:
 determining a display frequency for each region including one or more pixels in an image frame at each playback position of a video, based on a display range indicated by each of a plurality of pieces of display range information stored in a storage device, each of the plurality of pieces of display range information indicating the display range to be displayed on a display within a corresponding one of image frames constituting the video at a specific playback position of the video, the display range being variable depending on each playback position of the video; and   determining, for each playback position of the video, particular display range information to be provided to a terminal device, the particular display range information indicating a display range including one or more regions having highest display frequencies among the determined display frequencies.   
     
     
         7 . The information processing method according to  claim 6 , further comprising:
 determining an average display frequency for each playback position by averaging a plurality of the display frequencies determined for the each region included in the display range indicated by the display range information; and   determining, from among a plurality of pieces of the display range information stored in the storage device, one or more pieces of display range information respectively indicating one or more display ranges having highest average display frequencies among the determined average display frequencies, as the particular display range information to be provided to the terminal device.   
     
     
         8 . The information processing method according to  claim 6 , further comprising:
 generating a table for registering the determined display frequency for each playback position and region;   calculating, for each of the plurality of pieces of display range information stored in the storage device, a sum of the display frequencies for the each region included in the display range indicated by each of the plurality of pieces of display range information based on the generated table;   determining, as an attention degree, a value obtained by dividing the sum of the display frequencies by a number of the regions included in the display range indicated by the display range information, for each of the plurality of pieces of display range information stored in the storage device; and   determining, from among the plurality of pieces of display range information stored in the storage device, one or more pieces of display range information having highest attention degrees, as the particular display range information to be provided to the terminal device.   
     
     
         9 . The information processing method according to  claim 6 , further comprising:
 determining, for each playback position, a display range with a region having a highest display frequency as a center thereof or a display range with a median point of a plurality of the regions having highest display frequencies as the center thereof; and   determining display range information indicating the determined display range for each playback position as the particular display range information to be provided to the terminal device.   
     
     
         10 . The information processing method according to  claim 6 , further comprising determining the particular display range information indicating the display range including the one or more regions having highest display frequencies as display range information indicating a display range of a second video as a candidate to be displayed in the main view, the second video corresponding to a video identical to a first video displayed in a main view of the display of the terminal device and displayed in a sub view of the display.
